You prove a good point that caring about numbers is a bad thing and that I should focus more on individual people, but dude I don't even have that. People on my Reddit posts just say it looks cool, like bruh can you play the game please?
Is there a formula that makes games blow up, or at the very least have some YouTubers cover the game and give live feedback?
You've already discovered the formula: meme horror games. I count a total of twenty-six gameplay videos linked from the comments of your other three project pages, mostly for the two Siren Head games. That's a lot. When a YouTuber runs a generic search for "siren head" looking for something to entertain their audience, they will find your games in the list. Your original tower defense project will probably not get the same level of attention as those.
